I wouldn't consider this a Winnebago specific issue. Should have been posted in the Tech Talk section. 
Try a different digital meter.

It is a pseudo sine wave so will show less than 120 because the peaks on the sine wave are flat

Low output voltage generally means low input.  Check your bayyeries to be sure there at leasy 12.6 VDC

The voltage is correct at 95 vac.

Low voltage on inverter
« Reply #7 on: January 09, 2018, 12:28:20 PM »
My inverter has 95 volts from hot to nuteral and 120 volts from hot to ground
What is wrong??

My guess would be that the inverter is shot.

I think I found my problem I traced the out put from the inverter and it runs directly to the rear tv only   I couldnít find a lead to the front tv from the inverter   I donít know why not to the front  next to the inverter
This is a 2004 Brave maybe someone has done some rewiring but I did t see any signs of that
Iím thinking of just taping into the line that goes to the rear and install a new plug for the front tv

You need a voltmeter that will read true RMS, most inexpensive multimeters do not have that ability.

According to the Body, 110 Volt Wiring Diagram for your coach the front TV should be plugged directly into the inverter and another wire from the inverter should run to an outlet for a satellite receiver in front and then to the outlet for the bedroom TV.

You may also find the TV/VCR, Front Wiring Installation diagram for your coach helpful.

If you have a MSW inverter, and do not have a true RMS volt meter (they're quite pricy), the readings from the meter will not be very meaningful. It reads the average voltage, and then displays a calculated RMS value, which is accurate if it is measuring a true sine wave, and can be very inaccurate for any other waveform.

Two (or maybe three) possibilities:

1. There is some stray voltage on the neutral. Measure voltage from neutral to ground to check for that.
2. The inverter is kaput
[3. Are you sure you measured right?]

If this is a modified sine inverter you probably don't have a problem. Common (cheap) meters don't work on  square wave inverters.  It require as true rms Voltage meter (expensive).

Near all digital meters are true RMS, regardless of price. Even the $4 el cheapo Harbor Freight VOMs give RMS readings.

Besides, he is comparing two voltages, so the comparison is valid even if the reading is false. He is seeing different readings for neutral vs ground, so something is out of whack.

cbeierl is right, the front TV plugs directly into the inverter

Iíve found another problem I had with the inverter. It has a ground fault switch on the front of the inverter when I pushed the test button nothing nothing happened and there wasnít any power at the rear 120 volt plug pushing the reset didnít do anything either   
By accident I shorted the rear plug and tripped the ground fault I then pushed the reset button and all was good there was power again at the rear plug
If I pushed the test button the reset would not work until I shorted the rear plug
I have now reset the ground fault and not going to touch the test button anymore

Thanks to everyone for the great advise I have received and again sorry John for the multiple posts
